hey guys, proud to say i just picked up my first android device after being a blackberry fannatic for so long. Now my question and concern is the ram usage of my device: basically it is saying that 477mb of ram which seems like a lot for havong zero applications open. Is this normal? The galaxy tab we got at work on display (i work retail) shows around 320 mb of used ram only, so im slightly concerned. Thank you, Eric C.
